I took a look at the top 1000 girls (and boys names - because I was at it) in the US in 1912. This is what jumped out at me right away - I probably missed a few though.

For the US you can go to this link: http://www.ssa.gov/oact/babynames/limits.html and download US used name lists starting in 1880. It will list every name used more than 4 times. It will show you if it was used and how often (just no necessarily the popularity standing).
